STERILIZING DEVICE.

Application filed May 18, 1912.

T 0 all whom it may concern.

Be it known that we, JOHN J. HARDIE and FREDERICK N. Krs'rnnn, both citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sterilizing Devices, of which the following is a specification.

This invention relates particularly to sterilizing-devices adapted for quite general use, as on soda-fountain counters, in the oflices of physicians and surgeons, and in other locations too numerous to mention.

The primary object of the invention is to provide an improved and simplified sterilizing-device which can be manufactured at small expense, which is durable and handy, and which is adapted to serve its purpose without the necessity of constant attention.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which-- Figure 1 represents a vertical sectional view of a sterilizing device constructed in accordance with this invention, Fig. 2, a broken vertical sectional view taken as indicated at line 2 of Fig. 4 and showing a detail of the connection of the water-supply pipe through which water is supplied to the sterilizing chamber; Fig. 3, a broken horizontal sectional view taken as indicated at line 3 of Fig. 1, and showing the detail of the Bunsen burner employed; Fig. 4, a plan view of the improved sterilizing device; and Fig. 5, a section taken as indicated at line 5 of Fig. 1.

In the preferred embodiment of the invention there are employed a base A, from which rise a water-supply pipe A which serves to supply the sterilizing-chamber, a water-supply pipe A which serves to supply the cold-water chamber, and a wastepipe A which serves to drain an overflow chamber; and a vessel B, which is supported by the pipes mentioned and is provided with a sterilizing-chamber B a coldwater chamber B and an annular overflowchamber B The base A is preferably formed hollow, comprising a disk 1 having a downturned flange 2. The structure generally is in the form of a tripod, the three pipes A A and A being equally spaced and serving as legs Specification of Letters Patent.

or standards for the body or vessel B. The lower ends of the pipes mentioned are threaded and pass freely through openings in the top disk 1 of the base, where they are fitted with nuts 8, which serve to secure the pipes to the base. To the lower ends of the pipes are connected by unions or elbows 4, horizontally-disposed pipes A A A,, respectively, which extend out through openings in the vertical flange 2 of the base, the pipes A and A being fitted with valves 5 adapted to control the inflow of Water.

Mounted centrally on the base is a Bunsen burner 6, which is thus disposed beneath the sterilizing-chamber B The Bunsen burner has a gas-supply pipe 7 and airinlets 8 controlled by a sleeve or register 9.

The chamber B is in the form of a cylindrical member provided with an enlarged base-portion 10 and a bottom 11, from the peripheral portion of which depends a flange 12. The overflow chamber B encircles the cylindrical upper portion of the chamber B Thus, the upper portion of the wall of the chamber B forms an inner flange or wall 13 for the overfiow-chamber B The pipe A connects wit-lithe bottom of the annular chamber B as shown in Fig. 1. The walls of the chamber B are cast integrally with the walls of the chamber B and the chamber B projects laterally from the outer wall of the chamber B The outer wall of the chamber B at fords an annular flange 14, and'this flange is out down or reduced somewhat, as shown at 14*, to permit water to overflow from the chamber B to the overflow-chamber B With the upper end of the supply-pipe A communicates a goose-neck tube 15, through which cold water is delivered to the rinsing or cooling'chamber B The pipe A is connected atits upper end with the base wall of the overflow-chamber B and communicates, through a passage 16, with the interior of the sterilizing-chamber B The manner of using the device may be explained briefly. A flame is maintained beneath the chamber B by means of the Bunsen burner 6. Water is admitted through the pipe A to the sterilizing-chamber B where it is kept boiling; and in case of excess of water, as wherethe valve ofthe pipe A is left slightly open, the water will, overflow. the flange 13 into the chamber B and pass off through the waste-pipe A Water is supplied to the chamber B through thevpipe A and, if desired, the valve 5 of the pipe A may be left slightly open to maintain a constant flow of water into the chamber B from which the overflow passes over the flange 14; into the an nular'chamber B my be dipped in the boiling water in chamber B and then rinsedor cooled in the cool ing-chamber B In fact, the chamber B i may serve as a tray to hold the spoons or implements until their use is required, although, preferably, the tray is purposely made'so small that the spoons or implements will ordinarily be returned to the sterilizing-chamber. .It may be added that the gut-ter of the overflow chamber is pun p'osely removed from the wall of the sterilizing-chamber, so that the cold water'overflowing from the chamber A will not cool the sterilizing-chamber.

The sterilizing device of the character described is an exceedingly handy device, thoroughly adapted to its'purpose, and it may be manufactured at low cost.

The foregoing detailed description has been given for clearness of understanding,

and no undue limitation should be understood therefrom, but the appended claims should be constructed as broadly as permissible in view of the prior art.

' What we regard as new, and desire to secure by Letters Patent, is

1. A sterilizing-device comprising a sterilizing-chamber, an overflow-chamber at the upper portion thereof, means for applying heat to the sterilizing-chamber, means for supplying water to the sterilizing-chamber, and means for conductingwater from the overflow-chamber.

2. A sterilizing-device comprising a sterilizing-chamber, anoverflow-chamber encircling the upper portion of the sterilizingchamber, a cold-water chamber provided with an overflow, means for conducting wa ter from the overflow-chamber, means for supplying water to the cold-water chamber, means for supplying water to the sterilizingchamber, and means 'for supplying heat to the sterilizing-chamber.

3. A sterilizing-device comprising a base, water-pipe rising therefrom, and a body supported by said pipes and comprising a sterilizing-chamber and an overflow-chamber, the sterilizing-chamber communicating Spoons or implements cling the upper portionof the sterilizingchamber, and a cold-water chamberadjacent the overflow-chamber and communicating at its upper portion therewith, said pipes communicating, one with the sterilizing-chamher, and one with the overflow-chamber, and the third one serving to supply the cold-water chamber.
